Ian, that Model T is a work of art.
Now let's see what direction the pre-judging, speculation & assumptions will take now...
No matter what axiom does or doesn't do certain individuals will continue to make jabs strictly because it is in their nature ,they love conflict.
Many speaker manufacturer's use the resonance of the cabinet as part of its sonic signature and said resonance is by design. In my opinion given the surface area and size of drivers the M80 doesn't require bracing. If I could hear this resonance I would be upset,but alas I cant,and seriously using an accelerometer to prove resonance is ridiculous.
Axioms are a fantastic value for what you get and if you don't like what's on offer their are more than enough choices to go around.
